2010-05-14gss_krb5: handle new context format from gssdKevin Coffman
For encryption types other than DES, gssd sends down context information in a new format. This new format includes the information needed to support the new Kerberos GSS-API tokens defined in rfc4121.

2010-05-14gss_krb5: import functionality to derive keys into the kernelKevin Coffman
Import the code to derive Kerberos keys from a base key into the kernel. This will allow us to change the format of the context information sent down from gssd to include only a single key.

2010-05-14gss_krb5: add ability to have a keyed checksum (hmac)Kevin Coffman
Encryption types besides DES may use a keyed checksum (hmac). Modify the make_checksum() function to allow for a key and take care of enctype-specific processing such as truncating the resulting hash.

Make the client and server code consistent regarding the extra buffer space made available for the auth code when wrapping data. Add some comments/documentation about the available buffer space in the xdr_buf head and tail when gss_wrap is called.

2010-05-13netfilter: remove unnecessary returns from void function()sJoe Perches
This patch removes from net/ netfilter files all the unnecessary return; statements that precede the last closing brace of void functions. It does not remove the returns that are immediately preceded by a label as gcc doesn't like that.

2010-05-12mac80211: don't process work item with wrong frameJohannes Berg
When we process a frame, we currently just match it to the work struct by the MAC addresses, and not by the work type. This means that we can end up doing the work for an association request item when (for whatever reason) we receive another frame type, for example a probe response. Processing the wrong type of frame will lead to completely invalid data being processed, and will lead to various problems like thinking the association was successful even if the AP never sent an assocation response. Fix this by making each processing function check that it is invoked for the right work struct type only and continue processing otherwise (and drop frames that we didn't expect). This bug was uncovered during the debugging for https://bugzilla.kernel.org/show_bug.cgi?id=15862 but doesn't seem to be the cause for any of the various problems reported there.

The ip6mr /proc interface (ip6_mr_cache) can't be extended to dump routes from any tables but the main table in a backwards compatible fashion since the output format ends in a variable amount of output interfaces. Introduce a new netlink interface to dump multicast routes from all tables, similar to the netlink interface for regular routes. Signed-off-by: Patrick McHardy <kaber@trash.net>
2010-05-11ipv6: ip6mr: support multiple tablesPatrick McHardy
This patch adds support for multiple independant multicast routing instances, named "tables". Userspace multicast routing daemons can bind to a specific table instance by issuing a setsockopt call using a new option MRT6_TABLE. The table number is stored in the raw socket data and affects all following ip6mr setsockopt(), getsockopt() and ioctl() calls. By default, a single table (RT6_TABLE_DFLT) is created with a default routing rule pointing to it. Newly created pim6reg devices have the table number appended ("pim6regX"), with the exception of devices created in the default table, which are named just "pim6reg" for compatibility reasons. Packets are directed to a specific table instance using routing rules, similar to how regular routing rules work. Currently iif, oif and mark are supported as keys, source and destination addresses could be supported additionally. Example usage: - bind pimd/xorp/... to a specific table: uint32_t table = 123; setsockopt(fd, SOL_IPV6, MRT6_TABLE, &table, sizeof(table)); - create routing rules directing packets to the new table: # ip -6 mrule add iif eth0 lookup 123 # ip -6 mrule add oif eth0 lookup 123 Signed-off-by: Patrick McHardy <kaber@trash.net>
